After virtualization, virtual machines are completely isolated from each other, with independent CPU, memory, disk I/O, and network I/O. If any virtual machine fails, other virtual machines on the same physical machine are not affected, and the operating systems between different virtual machines can be heterogeneous.

Fully integrated virtualization framework

Wide compatibility, open cooperation

H3C CAS is widely compatible with third-party software and hardware platforms, including mainstream x86 and ARM servers, Intel/AMD/Kunpeng CPUs, storage arrays, native operating systems, network cards, HBA cards, etc. H3C CAS can smoothly integrate with third-party OpenStack architecture cloud platforms through customizable northbound REST APIs; H3C CAS has deep cooperation with manufacturers such as AsiaInfo Security, Hongshan, Aishu, and Zhongbiao Software, working together with partners to provide comprehensive integrated solutions.

H3C CAS virtualization platform architecture

The H3C CAS virtualization platform adopts a bare metal architecture to achieve virtualization management of hardware resources such as computing, networking, and storage in the data center, and provide automated services for upper level applications. Its business scope includes: virtual computing, virtual networks, virtual storage, high availability (HA), dynamic resource scheduling (DRS), virtual machine disaster recovery and backup, virtual machine template management, cluster file systems, virtual network policy management, etc.

The H3C CAS virtualization platform provides API interfaces for external integration with third-party platforms. H3C CAS adopts a virtualization solution based on KVM technology and a virtualization management solution based on OpenStack architecture. It can be upgraded with the Linux version upgrade, and there is no need to bind and install OpenStack related components during deployment.

Cluster based centralized management

The H3C CAS virtualization platform organizes server hosts and virtual machines into clusters, providing a clear hierarchical view that intuitively displays the relationships between data centers, host pools, clusters, hosts, and virtual machines, greatly simplifying the workload of resource management.

The benefits of centralized management based on clusters are:

By utilizing centralized management functions, administrators can organize, monitor, and configure the entire IT environment through a unified interface, thereby reducing management costs.

A cluster with a shared resource pool formed by the aggregation of multiple independent server hosts not only reduces management complexity, but also has inherent high availability. By monitoring all hosts in the cluster, once a host fails, the H3C CAS virtualization platform will immediately respond and restart the affected virtual machine on another host in the cluster. It can also perform manual online virtual machine migration, providing storage online migration function, supporting virtual machines to migrate online across different storage types and storage products from different vendors. It can migrate running virtual machines from one storage location to another in real time without interruption or downtime, providing users with an economical and effective high availability solution.

H3C CAS supports dynamic resource allocation function, which can dynamically adjust virtual machine resources (CPU, memory, disk, network card, etc.) online/offline.

Cluster based hierarchical management model

Complete virtual machine lifecycle management

H3C CAS adopts a bare metal architecture, which allows for the construction of a virtualization platform without the need to bind an operating system. The Hypervisor structure is streamlined, and the deployed storage space is less than 200M. Compatible with mainstream servers and storage, supporting mainstream operating systems such as Windows, CentOS, Redhat, Suse, macOS, etc.

Supports common functions such as creating, modifying, starting, pausing, restoring, hibernating, restarting, shutting down, powering off, cloning, migrating, and snapshot of virtual machines. It also supports remote connection to virtual machines through the console of the management interface, and all operations are based on a graphical configuration interface.

Virtual Machine Lifecycle Management Phase

High availability (HA)

The H3C CAS virtualization platform provides cluster based centralized management of data center IT infrastructure. Clusters formed by aggregating multiple independent server hosts not only reduce management complexity, but also have inherent high availability, providing users with an economical and effective high availability solution.

H3C CAS virtualization platform HA continuously monitors the virtual machines in the resource pool. H3C CAS maintains a "heartbeat" between each virtual machine uniformly. When a virtual machine loses its "heartbeat", it will attempt to restart the failed virtual machine on other servers. When the server hosting the virtual machine crashes, the virtual machine can immediately automatically restart and continue running on other servers in the cluster, providing unexpected downtime protection with a business interruption time of minutes. The HA function of virtual machines requires support for various specifications of virtual machines. H3C CAS adopts an optimized high-performance cluster file system, which supports storage protocols such as SAN/iSCSI/NFS, allowing different servers to access the same virtual machine disk files. This feature makes the implementation of H3C CAS HA very simple and convenient.

Using HA features for host failover

Dynamic Resource Scheduling (DRS)

In a virtualized environment, once a user integrates an application onto a physical host with fewer resources, the resource requirements of the virtual machine often become a bottleneck, and the total resource requirements are likely to exceed the available resources of the host. The dynamic resource scheduling feature provided by the H3C CAS virtualization platform introduces an automation mechanism that continuously balances capacity and migrates virtual machines to hosts with more available resources, ensuring that each virtual machine can call the corresponding resources in a timely manner at any node. Even with a large number of virtual machines running SQL Server, as long as the dynamic resource scheduling function is enabled, there is no need to monitor CPU and memory bottlenecks one by one. The fully automated resource allocation and load balancing functions can also significantly reduce the costs and operating expenses of data centers. H3C CAS supports dynamic load balancing for virtual machine storage, determining the optimal location for virtual machine data to reside during creation and use based on storage characteristics. It can automatically migrate without interruption according to storage volume performance and capacity, eliminating storage risks.

The dynamic resource scheduling function monitors the utilization of computing resources such as CPU and memory of hosts in the cluster through a heartbeat mechanism, and determines whether to find a host with more available resources in the cluster based on user-defined rules, in order to migrate the virtual machines on the host to another server with more suitable resources, or migrate other virtual machines on the server, thereby ensuring the resource requirements of a critical virtual machine.

dynamic resource scheduling

Dynamic Power Management (DPM)

The H3C CAS virtualization platform supports monitoring the utilization of resources such as CPU, memory, and connections of physical hosts in the cluster. By dynamically migrating virtual machines and shutting down idle servers, the energy consumption of the data center can be reduced, thereby achieving energy conservation and emission reduction for users. When the business load in the cluster increases, it can automatically wake up previously shut down idle servers and achieve cluster load balancing through dynamic migration of virtual machines.

Flexible resource allocation mechanism

According to business needs, the H3C CAS virtualization platform supports on-demand allocation of computing resources, network resources, and storage resources. The allocation of computing resources is achieved through resource quotas and reservation techniques for virtual CPUs and virtual memory. The allocation of network resources is achieved through the QoS function of virtual switches, while the allocation of storage resources is achieved through the limiting function of virtual machine disk IOPS (Input and Output Per Seconds) and throughput. By using these technologies to meet SLA (Service Level Agreement), high priority virtual machines are ensured to have better computing, network, and storage performance, avoiding the "proximity interference" effect between virtual machines.

Unified management and scheduling of GPU resources

The H3C CAS virtualization platform supports GPU resource pool functionality, which enables unified management and scheduling of physical GPUs and vGPUs. Through two modes of GPU direct access and GPU virtualization, GPU resources are graphically allocated and released, enabling virtual machines to dynamically allocate and release GPU resources from the GPU resource pool on demand. This provides fast and efficient GPU resource supply capabilities for high-performance computing services in industries such as broadcasting, earthquake, meteorology, and design, reducing operational management complexity.

Unified management and scheduling of GPU resources

Raw Device Mapping (RDM)

H3C CAS supports storage protocols such as SAN/iSCSI/NFS, supports virtual volume functionality, and abstracts external storage.

The H3C CAS virtualization platform supports direct mapping of SAN storage (FC or SCSI) LUNs to virtual machines. When building a cluster file system, virtual machines can directly access raw devices and store virtual machine data directly on the LUNs.

Distributed dual stack firewall

The H3C CAS virtualization platform supports both IPv4 and IPv6 addresses. When creating a virtual machine, select the address type according to the requirements and customize the virtual firewall rules. Distributed virtual firewalls lower the security boundary of data centers to the virtual switch level. Building a secure firewall based on virtual network cards of virtual machines not only provides different security policies for different virtual network cards, but also achieves an ideal balance between performance and flexibility. When virtual machines migrate between different physical nodes, the security policies move accordingly.
